That looks like some Lisp-1 (Scheme-type) dialect.

  For now, I'm using, IIRC, "NewLisp" and

( setq SETQ   setq   )
( SETQ NULL   null?  )
( SETQ ATOMP  atom?  )
( SETQ T      true   )
( SETQ CAR    first  )
( SETQ CDR    rest   )
( SETQ PROGN  begin  )
( SETQ LENGTH length )
( SETQ COND   cond   )
( SETQ APPEND append )
( SETQ CADR( lambda( X )( CAR ( CDR X ))))
( SETQ CADDR( lambda( X )( CAR ( CDR ( CDR X )))))

  . I was not able to convert "lambda" to uppercase, though.
  So, I have to write:

( SETQ DIFF
  ( lambda( X )
    ( COND
      ...
